Abstract

A method and system provide a fitting system for a flexible fuel cell of an aircraft. The fitting system may include a flexible fuel cell and a fitting. The fitting may have a peripheral flange with a series of slots spaced about the flange. A series of fabric strips may be threaded into the slots of the fitting and one or more adhesives may couple the fabric strips to the fuel cell. The fabric strips may extend out around the periphery of the fitting to provide a uniform contact surface area with the fuel cell. The fabric strips may be separated by fuel cell material. The fabric strips may be made from one or more materials for enclosing or holding fuel. The fitting may further include threaded holes wherein the threaded holes may receive fasteners to couple the fitting to the fuel equipment of an aircraft.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A fitting system for a flexible fuel cell of an aircraft comprising:
 a flexible fuel cell; 
 a fitting with a peripheral flange having a series of slots spaced about the flange; 
 a series of fabric strips threaded into the slots of the fitting; and 
 one or more adhesives that couple the fabric strips to the fuel cell. 
 
     
     
       2. The system according to  claim 1 , wherein the fabric strips extend out around a periphery of the fitting to provide a uniform contact surface area with the fuel cell. 
     
     
       3. The system according to  claim 1 , wherein the fabric strips are separated by fuel cell material. 
     
     
       4. The system according to  claim 1 , wherein the fabric strips are comprised of material for enclosing or holding fuel. 
     
     
       5. The system according to  claim 1 , further comprising threaded holes. 
     
     
       6. The system according to  claim 5 , wherein the threaded holes receive fasteners to couple the fitting to fuel equipment. 
     
     
       7. The system according to  claim 6 , wherein the fuel equipment comprises at least one of a gauge, a breakaway valve, a vent valve, and an access plate. 
     
     
       8. The system according to  claim 1 , wherein the fuel cell is coupled to the aircraft, the aircraft comprising at least one of an airplane, helicopter, a hover craft, and a drone. 
     
     
       9. The system according to  claim 1 , wherein the fitting is made out of a metal. 
     
     
       10. The system of  claim 1 , wherein the slots have an elliptical shape. 
     
     
       11. A fitting system for a flexible fuel cell of an aircraft comprising:
 a fitting with a peripheral flange having a series of slots spaced about the flange; 
 a series of fabric strips threaded into the slots of the fitting; and 
 a series of holes spaced at a distance from the flange and the slots and positioned closer to a geometrical center of the fitting compared to the flange and slots. 
 
     
     
       12. The system of  claim 11 , further comprising a flexible fuel cell, the fitting being coupled to the flexible fuel cell. 
     
     
       13. The system according to  claim 12 , wherein the fabric strips extend out around a periphery of the fitting to provide a uniform contact surface area with the fuel cell. 
     
     
       14. The system according to  claim 13 , wherein the fabric strips are separated by fuel cell material. 
     
     
       15. The system according to  claim 11 , wherein the fabric strips are comprised of material for enclosing or holding fuel. 
     
     
       16. The system according to  claim 1 , wherein the holes further comprise threads. 
     
     
       17. The system according to  claim 16 , wherein the threads receive fasteners to couple the fitting to fuel equipment. 
     
     
       18. The system according to  claim 17 , wherein the fuel equipment comprises at least one of a gauge, a breakaway valve, a vent valve, and an access plate. 
     
     
       19. The system according to  claim 12 , wherein the fuel cell is coupled to the aircraft, the aircraft comprising at least one of an airplane, helicopter, a hover craft, and a drone. 
     
     
       20. The system according to  claim 11 , wherein the fitting is made out of a metal.
